SRECIFICATION forming part of Letters Patent No. 270,145, dated January 2, 1883.

To all lwhom 'it may concern: I

Be itknown thatI, FRANZ XAVER STIEF- ENHOFER, of South Easton, county of Northampton, and State of Pennsylvania, haveinvented a new and useful Improvement in Wheat-Scouting Apparatus, of which the following is a specication.

This invention relates to machines for cleaning wheat and other cereals by rasping off the cortical portion; and the nature of it consists in a wheat. decorticating and scouring machine which will deprive the wheat-grains of their cortical envelopes in "a -veryefflcient and thorough manner, as will be fully understoodH from the following description, when taken in connection with the annexed dra wings,in which- Figure l is a perspective view of my wheatscouring machine complete. Fig. 2 is a vertical section taken centrally and longitudinally through the machine. Fig. is a transverse section taken through the machine in the vertical plane indicated by dotted line :v a: on Fig. 2. Fig. 4 is a side view'of the slotted oscillating regulating discharging-shaft detached from the machine.

The letter L designates the rectangular frame ofthe machine, "which is provided with a suitable housing for inclosing' the decortieating devices. At the top of thisfra-me is a hopper, I, which has for its bottom an adjustable slide, H, for regulating the feed according to the quality of the grain and the condition thereof. Below the feed-opening of the hopper I secure to a horizontal shalt, A, on which are belt-pulleys F G, a numberol` wheels or disks, D, the faces of which are rugated, serrated, or roughened in any suitable manner. These disks or wheels are made of hardened steel or of any other suitable material. Between these rugated or roughened disks are stationary plates E,'which are rigidly secured to the main frame, or they are what might be denominated concavesi' Below the shaft A and its decorticators 'or scourers, and arranged in a plane parallel to said shaft A, is anothershaft, A', having its bearings in the frame L, and provided on one end with a beltpulley, J, which revolves in the same direction as the pulley F on shaft A, by means of-a belt. (Shown in Fig. 1.) On this shaft A', I secure disks or wheels D, corresponding to the disks or wheels D on shaft A, but arranged to ro- "tate between them, and also between the sta- "base of frame L, and it is 4provided with a handle, B',` on one end, by which it can be -oscillated for the purpose of regulating the outward flow of the cleaned grain. This outward How is regulated by adjusting the upper part of the slot() with relation to the internal edge, a, of the bottom concave, as indicated by Fig. 3. Thisdevice B enables me to regu! late the flow ofthe grain from the machine at will and retain any given body or mass of grain in the decorticator until it has been thoroughly cleansed or deprived of the cortical parts.

The operation of the machine may be brieiiy described as follows: When power is applied to the upper shaft, A, it is transmitted to the lower shaft, A', by means ofthe belt and pulleys described. VThe grain to be treated is fed into the hopper I, and the feed is regulated by adjusting the inclined slide H up or down. Thegrain flows in athin stream through the feed-opening, and is evenly distributed to the revolving and stationary decorticating-surfaces, which rapidly and uniformly deprive it ot' the hull and germ,and allow it to be finally discharged through the longitudinal slot C, made through the shaft B.

l am aware that it is old in grain-scourcrs to employ rotary decorticating-disks in cotnbination with stationary decorticating-plates, and I do not therefore broadly claim such means for treating grain.

Having thus fully described my invention, what I desire to secure by Letters Patent is 1. The combination ofthe rotary roughened .disks on independent shafts, arranged horizontally, the stationary interposed roughened plates E, and the radially-adjustable shaft B,
